We've moved beyond the neurologist. She's on memantine and donepezil, now routinely prescribed by our primary provider under direction from the final neurologist we saw. She sees the PP once every 6 months. Frankly, I felt that our primary understands her problems better than the neurologists. They simply put her into a "some kind of undiagnosed cognitive impairment category" and continued the standard pills. We've been given no encouragement regarding any improvement and view the current situation as a stage that will last an undetermined period.
